CAN-SOLDERING APPARATUS.

SPECIFICATION forming part of- Letters Patent No. 283,821, dated August 28, 1883.

' Application nieaMay es, 1853. (no model.)

.To a/ZZ whom, it may concern:

Be it known that I, JosnPH D. SOHAFER, of De Soto, Missouri, have made a new and useful Improvement in Gan-Soldering Apparatuses, of which the following is a full, clear, and exact description, reference being had to the annexed drawings, making part of this specieation, in which- Figure 1 is an end elevation of the machine; Fig. 2, a plan showing a can in section upon the machine; Fig. 3, a longitudinal section; Fig. 4, an end elevation, looking toward the outer end of the parts shown in Fig. 3; Fig. 5, a section on the line 5 5 of Fig. 3,- Eig. 6, an edge elevation of the ring that supports the ring at the top of the can, and Fig. 7 a section on the line 7 7 of Fig. 3.

The same letters of reference denote ther same parts.

A represents a shaft, journaled at a in an upright, B, and adapted by means of the l1andle O to be rotated therein.

D represents an arm fastened to the shaft A.

A strip, E, which is preferably made of spring-steel, at one of its ends, e, and bymeans of the screws c c', is fastened to the arm D;

The other end, c, yof the strip is, by means of, say, the ears ci, (but one shown,) fastened to the fixed head E. This head is perforated at j f to admit the shaft Athat is, the head 'rests upon the shaft, but does not rotate there# with, The head consists, preferably, of the disks f f', united by the bar f2. A pin, G, projecting from the upright B, through the ring II into the disk f', Aserves to keep the head E from turning .1 ith the shaft A; The strip E in width is preferably nearly equal to the depth of the can being soldered, and in length fully equal, at least, to the circumference of the largest can that can be made on the machine. This strip E, thus supported and connected, forms an expansible mandrel, upon which the body of the can rests during the soldering operation, which is conducted as follows: The mandrel is rst reduced to a diameter smaller than that of thecollar i of the intended ean. This is accomplished by rotating the shaft A and arm D, so as to wind the strip E upon the fixed head F. The rotation of the shaft A is effected, as stated, by means of the handle C, and after the mandrel has been reduced, as desired, it is held from unwinding by means of the spring-dog c, which enters one of the notches b in the upright B. The collar i of the can is then passed overthe, mandrel and hung upon the rest 7L of the ring H.- The body c" of the can is then passed onto the mandrel and its edge t2 made to catch under the flange 3 of the collar z'. The pieces constituting the body i are suitably curved before being placed on the mandrel. After the part i has been connected with the collar o', as described, the dog c is detached and the handle C turned backward until the mandrel has eX- panded to fill the body fl. This serves to sup port the body i. The bottom i is then attached, and the soldering is proceeded with. The body-seam may iirst be soldered, and the body, opposite the body-seam, soldered to the collar 'i and bottom t, The handle C is then turned to reduce the mandrel sufficiently to allow of the can being turned around upon the mandrel, and forthe purpose of enabling the soldering of the remaining` seams to be accomplished.- The can is then slipped off the inandrel and the operation repeated. The rest h of the collar-ring His radially adjustable, the rest being attached to the stem h,which passes through the beating hZ of the ring and is encircled bythe ','pring h3. This enablesthe rest to be readily adjusted to the collar t', and the collar, when upon the rest, and the body lL",to be readily relatively adjusted, so that the edge `i2 can be readily made to catch in the collar. The said seat is self-adjusting-that is to say, the spring operates at all times to draw the rest outward or from the center of the ring. The ring II turns upon the bearing or center, The ring H may have another rest, kilopposite to the rest h, and for asimilar purpose; and, if desired, lit may be made similarly adjustable. TheuprightB is preferably pivoted in the foot B', to enable the upright to be swung aroundto present the mandrel in any direction.

The present device is adapted for soldering many other articles as well as cans.

I claim- 1. The combination, in a can-soldering apparatus, of the expansible portion E with the spring-actuated rest h and the ring I-I, substantially as described.

2. The combination of an eXpansible por- IOO 2 esami tion, E, the shaft A, having its bearing in the Y 4. The combination of the exible strip E, upright B, the handle C and its dog @,the arm the head F, and means for holding this head 1o 1), head F, and pin G, substantially as deagainst turning, substantially as described.
